The PlayStation Network video service has been open for about eight months now, and it continues to grow. Users will find an expanded selection today, with two new partners joining the service: VH1 and Nickelodeon. Now PS3 and PSP owners will be able to download Avatar, iCarly, Invader Zim, SpongeBob SquarePants, Confessions of a Teen Idol, Sober House, and more. As usual, SD episodes cost $1.99 each.

In addition to the new content providers, NBC and PlayStation have teamed up to provide the pilot episode of NBC's new series, KINGS, free for PS3 and PSP owners. Simply visit the PlayStation Store and you'll be able to download the 80 minute debut in SD or HD for free.
